Russia’s Only Aircraft Carrier Huge Floating Dry Dock Accidentally Sunk. one of the world’s largest floating dry docks, known as PD-50, has sunk while Russia’s aircraft carrier Admiral Kuznetsov was aboard. According to reports, the dry dock began to sink suddenly, collapsing cranes onto the carrier’s deck and sending shipyard workers scrambling for their lives.

The dry dock is located at 82nd Repair Shipyard in the village of Roslyakovo. The shipyard there primarily supports Russia’s Northern Fleet based out of nearby Severomorsk.

A photo taken today from the 35th Ship Repair Yard, where the Kuznetsov was towed, shows the crane still laying on the flight deck of the Kuznetsov. Rakhmanov said the repairs to the deck should only take a week and a half.https://t.co/XhX9awN9Kfpic.twitter.com/ncQXPVfa2R

We don’t know exactly how many people were hurt or killed in the incident, but apparently, there were casualties. According to Russian media outlets,” the vessel suffered no damage after the incident at the 82nd shipbuilding plant.”

There are reports that there was some kind of accident at the 82 Ship Repair Plant with the Admiral Kuznetsov. Apparently, its PD-50 floating dock, sank suddenly while workers were on it, and caused two cranes to collapse. One worker is reported missing.https://t.co/zAhZ4Qydj4pic.twitter.com/k35480iqI8

The most recent reports state that “two victims remain in hospitals, two received outpatient care, another person went missing.” As for the carrier’s condition, officials from the shipyard claim the Kuznetsov is undamaged and that her refit schedule will not be affected. At the same time, Russian outlets are now reporting that a five-meter gash was made in the hull of the ship around the waterline and that the deck was supposedly opened up with intricate machinery exposed when the crane fell on it.

Admiral Kuznetsov is currently undergoing a much-needed complex overhaul after years of deferring the project. Even the ship’s notorious boilers have been pulled and new ones are being installed (see below). The aircraft carrier is tentatively scheduled to return to the fleet in 2021, but judging by other deep overhauls of large and complex Soviet-era fighting ships, it could end up taking significantly longer.

So once again, take all this with a tall shot of vodka as it seems very early for anyone to make the claim that everything will proceed as normal.

The fate of the dry dock—the only one of Russian origin that can accommodate the aircraft carrier—also remains unknown. If it was badly damaged, that alone could spell major trouble for the Kuznetsov’s future.
